High-temperature, flexible, thermal barrier seal

摘要

This device seals the sliding interfaces between structural panels that are roughly perpendicular to each other or whose edges are butted against one another. The seal is mounted in a rectangular groove in a movable structural panel and comprises a plurality of particles or balls densely packed in an outer sheathing. The balls are laterally preloaded to maintain sealing contact with the adjacent wall using a pressurized linear bellows. Distortions in the adjacent panel are accommodated by rearrangement of the particles within the outer sheathing.
